[Brief explanation of the drawing]

Figures 1 to 3 show an embodiment of the present invention, Figure 1 is an overall perspective view with some parts omitted, Figures 2 and 3 are left and right enlarged side views, and Figure 4 is a conventional example. It is a perspective view with a part omitted. 1 is a chassis, 2 is a cassette lid, 3 is a spring, 4 is a lid closing mechanism, 5 is a lid opening operating tool, 6 and 6' are detection levers, 7 is an interlocking mechanism, and 8 is an interlocking metal fitting.

Claims (1)

[Claims for Utility Model Registration] A cassette lid 2 is pivotally attached to a chassis 1 equipped with a tape transport so as to be able to swing open and close, and a spring 3 biases the cassette lid 2 in the swing opening direction.
A lid closing mechanism 4 for locking and holding the cassette lid 2 in the closed position against the urging force of the chassis 1 and a lid opening operation tool 5 for releasing the locking of the lid closing mechanism 4 are provided on one side of the chassis 1. , at least the chassis 1
In a cassette lid opening/closing mechanism for a cassette type tape recorder in which a detection lever 6 that can be freely inserted into and removed from the tape groove is provided at a position near the other side, the detection lever 6 is located opposite to the side on which the closing mechanism 4 and the opening operating tool 5 are located. The cassette lid 2 is attached to the side of the chassis 1 on the side.
A cassette lid opening/closing mechanism for a cassette type tape recorder, comprising an interlocking mechanism 7 for automatically and reversibly moving the detection lever 6 out of the tape groove in conjunction with the swinging opening movement of the tape recorder. The interlocking mechanism 7 is caused by the lever-shaped metal fitting 7A pivotably supported on the chassis 1 in a state where it is engaged with the detection lever 6, and the non-operation biasing spring pressure of the switch SW that responds to the detection lever 6. The spring 7B has strong spring pressure and swings and biases the lever-shaped metal fitting 7A in the direction of movement in which the detection lever 6 comes out of the tape groove, and the spring 7B contacts the cassette lid 2 in the closed lid position. Accordingly, the cassette lid opening/closing method according to the utility model registration claim 7 is constituted by a claw-like protrusion 7C that restricts the swinging of the lever-like metal fitting 7A against the swinging biasing force of the spring 7B. mechanism. The target recorder has detection levers 6 and 6' located near both sides of the chassis 1, of which the detection lever 6' on the side where the lid closing mechanism 4 and the lid opening operating tool 5 are located is located near the opening. The cassette lid opening/closing mechanism according to claim 1, which is registered as a utility model and is configured to be inserted into and removed from a tape groove in conjunction with the movement of a metal fitting 8 integrally connected to the lid operating tool 5.
